Hi sorry for late reply, I somehow had my notifications turned off. I'm using FSX but I understand this is only P3D compatible after I got a free copy of the scenery from a guy at aitraffic.ch named Vladik.

Ok, if I understood correctly, you obtained a (possibly outdated or otherwise broken?) version elsewhere. The issues could be down to many things, however, the first thing to check would be whether the scenery is indeed enabled and that there is no other scenery active for KDTW. The scenery is P3Dv4 compatible, but "64-bit" scenery sometimes works on 32-bit too, albeit with some caveats. Else there isn't that much that can be done apart from a sim upgrade to P3Dv4, I believe.
